Answer:
The correct answer is 61.
Step-by-step explanation:
Undergraduate enrollment at Stellar University in the year 2010 was 2720.
Undergraduate enrollment at Stellar University in the year 2015 was 3025.
Therefore in two years there was a (3025 - 2720 =) 305 increase in number of students at Stellar University.
We have to relate a linear model for enrollment over time. Let y be the enrollment and x be the time.
The linear model would look like y - 3025 = ( x - 2015)
Thus the slope of this line is given by = 61.

answer:
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Step-by-step explanation:
Sample size = 85 followed a vegetarian diet
Period = 4 months,
Mean systolic blood pressure= 124 mmHg
Sample size = 75 followed non-vegetarian diet
Period = 4 months
Mean systolic Bp = 138 mmHg
Reasons/explanations
Given that p -value < 0.01 we will reject the null hypothesis
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Answer: 346.4
Step-by-step explanation:
The whole triangle ABD is a 30-60-90 right triangle. In 30-60-90 triangles, the smallest side is x, the middle side is x, and the largest side/hypotenuse is 2x.
Side AB is the smallest side and therefore x=300. Side BD is the middle side and so we can use x and we get BD=300
=519.615
The question is asking for CD, and we know that CD can be equal to BD minus BC since that would isolate CD
Triangle ABC is also a 30-60-90 triangle but the 300 feet is the middle side in this triangle. So we can do 300=x and divide 300 by radical 3 and get that x=173.205
Side BC is the smallest side of this triangle so it would be x and x is 173.205.
Now that we have the whole side BD and the part of it BC. We can subtract BD by BC (519.615-173.205) and we get that CD=346.4
